Dane County Circuit Judge Maryann Sumi ruled Thursday that Republican legislators violated Wisconsin's open meetings law during the run up to passage. She says that renders the law void.
The law pushed by Gov. Scott Walker takes away all bargaining rights except over base salary for teachers and other public workers.
The decision is not the end of the legal fight. The state Supreme Court has scheduled arguments for June 6 to determine whether it will take the same case.
Lawmakers could also pass the law again in order to nullify open meeting concerns that led to the judge's ruling Thursday.
